摘要: 水稻(Oryza sativa L.)籼型光温敏核不育系FK1S是以丰39S为母本,以含抗稻瘟病基因pi2的VE6219为父本进行杂交的,经过合肥市和海南省三亚市连续6年12代南北穿梭加代种植,通过分子标记、定向低温加压和抗病性鉴定选择,于2016年通过安徽省农作物品种审定委员会鉴定。FK1S不育系育性稳定、起点温度较低、稻米品质优、配合力强、株型紧凑、抗病性较好、抗倒伏、繁殖制种产量高。

Abstract: Derived from the cross of feng 39S(as the female) and VE6219S(as the male),FK1S was bred through shuttle breeding in both Hefei and Sanya for 12 generations over six years. It was selected through molecular marker and under the conditions of low temperature stress. FK1S was certified by Anhui Provincial Crop Variety Release Committee in 2016. FK1S showed stable male sterility with low critical temperature on fertility alteration,relatively good grain quality,panicles with many spikelets,good blast resistance,high combining ability and favorable outcrossing habits,lodging resistance and high seed yield in multiplication.
